LONDON (AP) — The U.S. and China held a second day of talks Tuesday in London aimed at easing their trade dispute, after President Donald Trump said China is “not easy” but the U.S. was “doing well” at the negotiations.

China returns to trade talks with the U.S. holding, from its view, a strong hand: Its economy is bearing up better than expected. And it has an ace card: rare earths.

A new round of trade negotiations between the United States and China has started in London, with both sides trying to preserve a fragile truce brokered last month.
